WORK EXPERIENCE (cont.)
LexisNexis, Dayton, OH 2001 - 2005
Worked as a consulting software engineer for this leading provider of
solutions for the legal and news information markets. Key
accomplishments include:
. Worked on a flagship J2EE project to recode part of the LexisNexis
backend search infrastructure in Java on IBM WebSphere. Previously,
this was coded almost entirely in MVS assembler. This piece, search
normalization, was redesigned to run as a stateless session EJB while
maintaining communication with other appropriate assembler modules via
JNI, and also while accessing necessary disk files. This module also
had to be internationalizable, and perform its tasks withing a tight
processing timeframe budget, despite needing to eventually handle all
of LexisNexis search transaction volume. Currently, it performs its
tasks in an average time of slightly under 10 milliseconds per call.
Continued to work on this project to implement new features and
products.
. For the above project, also helped design and write the Ant build
process and scripts, and ClearCase source code layout.
. Worked on another flagship J2EE project to help extend more of the L-N
search infrastructure into the Java/J2EE environment on IBM WebSphere.
Again, this was designed as a set of stateless session EJB's
communicating with existing infrastructure (including the previously
mentioned search normalization EJB) to perform tasks including online
message processing and loading and activations, loading, and
deactivation of online search databases. Also helped develop the
team's Ant scripts and ClearCase layout for source code. Helped
mentor team members in Java/J2EE development and use of developer
tools, such as WSAD.
. Worked on a custom tool, WCT, designed to enable provisioning and
configuration of internally developed WebSphere applications to their
remote servers on Unix and Windows. Written entirely in Java, it was
cross platform and completely integrated into the Ant build/scripting
tool. This also utilizes numerous XML technologies, including XSLT.
. Worked as part of a team that investigated, prototyped and
disseminated information on Java/J2EE technologies throughout
LexisNexis. Out of this work came the company adoption of standard
developer tooling, such as WSAD for development and Ant for repeatable
builds, ClearCase for source code control, and many others.

Cardinal Solutions, Inc., Cincinnati, OH 1997 - 2001
Worked as a software engineering consultant for this highly regarded
consulting firm in Cincinnati, specializing in designing and developing n-
tier solutions for client companies. Key accomplishments include:
. Worked on a J2EE project for a large manufacturer that allows customers
to order spare parts for their components, to view repair bulletins, and
perform account management tasks all online. Part of a "common objects"
group that is responsible for designing, writing and deploying common
functionality for other developers on the project to use. Have written
Java Beans, EJB's and JSP's as part of this effort. Other technologies
in use include XML, the BEA Weblogic Bean Server, Rational Rose and
Together/J, as well as open source tools such as the Xerces XML parser
and the Ant "make"/scripting tool.
. Designed and developed key additions to the install process of a
flagship, cross platform PDM software system. Written in Java, the
install automates both the installation of selected system modules, and
the creation and initialization of large, complex databases. Previously,
only small sections of the install process were automated, and database
installation was primarily done manually. Designed and developed a
series of "Design Patterns" based classes to not only make install
overall, and database installation, more automated, but also included
functionality to "rollback" operations, or allow the user to retry, in
the event of a failure.
. Developed a ground breaking n-tier system for a large health insurance
provider in north Cincinnati that keeps track of patient clinical
history, and performs other important tasks such as pre-authorization of
procedures, and automation of reviews of acceptance/rejection decisions.
It utilizes DCE RPC's for communication to the server portion of the
system, large scale Sybase databases for data storage, a transaction
processing monitor (Encina), a custom written client program (written in
Visual C++/MFC for Windows NT), and custom written server processes
(written in C++ for AIX). My work on this system included:
. Worked on the client program for Windows NT, developing a number of
client features. Designed a set of classes to represent and encapsulate
the M&R (Milliman and Roberts) medical treatment guidelines, which are
used for specific combinations of conditions and treatments, and designed
and wrote the code for the UI representation. Later retrofitted this
same code so that it could be used by other developers in other parts of
the client. Worked on a number of other client software features as
needed. This development work involved heavy use of 'Design Patterns'
focused design and development, heavy use of the STL/C++ Standard
Library, use of 3rd party Active X controls, designing/writing code to
use DCE RPC's for communication to the server side of the system. Gained
experience in the use of UML diagrams for both class design and
documentation.

WORK EXPERIENCE (cont.)
Datalytics, Inc., Dayton, OH 1994-1997
Worked as a software engineer and software development team lead for this
developer of innovative solutions for Fortune 500 companies and for the
retail software industry. Key accomplishments include:
. Worked on the Teleres Workstation, a specialized n-tier online system
designed to be used by clients involved in the real estate investment
securities trading industry. The system was designed to be used with a
custom written, Windows NT based client software, with an automatically
load balancing set of server machines delivering both structured and free
text, unstructured data to the client. At the time Teleres was a
division of the Dow Jones Corporation, and the Teleres Workstation was
launched with full page ads in 'The Wall Street Journal' in late 1995 and
early 1996. Eventually became the development lead of the team
responsible for writing the client application (written in Visual C++) to
deliver electronic version of various print publications, as well as
articles from the Dow Jones newswire feed, to the client desktop.
Designed mechanisms to not only perform efficient searches on demand, but
to allow users to build and maintain 'profiles' to be used to
automatically 'push' content to the client desktop. Worked closely with
backend developers to determine capabilities and development strategy,
and worked with Teleres to determine future direction as necessary.
Also worked on a number of other smaller code components for use by
members of other teams as necessary. Together, the entire development
team working on the Teleres Workstation achieved a measured benchmark of
approximately 5 bugs per every 10,000 lines of code written.
. Later worked on the server processes for this same system, writing code
in C++ using the AIX compiler. Focused primarily on processes and
database tables that contained member data, which ranged into the mid
millions of rows. Also wrote server processes to deliver various types
of review data to the client, as well as performing reviews of virtually
all server code with DBA's to determine performance bottlenecks, and
provide remedying code and queries as necessary. The code/queries also
had to be retrofitted to allow for regular upgrades in terms of the
number of users of the system (as it was rolled out to new service
areas), as well as additional members (when the system was used for
members in additional states). Again, 'Design Patterns' and UML were
used extensively in design and coding. Also led changes to allow the
'read' server processes to use stored procedures (using Transact-SQL)
rather than hard coded SQL.
. Also performed a number of duties for a large retailing organization with
offices in Cincinnati. Worked on retrofitting a web based reporting and
appointment scheduling system for seasonal hiring from Netscape based web
servers to Microsoft IIS, where the system used Microsoft SQL for data
storage. Gained experience with Microsoft ASP technology.
. Worked on the design and development of the Blaze Web Performance Pack, a
'shrink wrapped' retail software package designed to speed web access
from ordinary browsers up to a theoretical limit of 8 times faster than
normal. Worked closely in the design of the algorithms used to access
and download treated web pages, designed and wrote proof of concept and
benchmarking code, and designed and wrote the code to perform 'on the
fly' decompression of treated web pages. Also designed and wrote code
for various parts of the client program, which was designed to work on
all flavors of 32 bit Windows. Gained experience in writing code to be
run from the 32 bit Windows system tray, code to interface to web
browsers, and in HTTP protocol extensions, as well as writing object
oriented C++ code.

Private Consulting 1994
Worked as a private consultant for a local branch of a large vendor of
terminal emulation and data communications software products. Key
accomplishments include:
. Wrote a number of protocol drivers for a flagship terminal emulation LAN
gateway product that uses a custom communications protocol, for clients
using Windows 3.x and the customer's custom data communications and
terminal emulation framework product. Code was written in C/C++ using
Microsoft Visual C++ version 1.5. The code had to process packets and
pass them through the framework in real time while not interfering with
other processing duties the user might be performing. Wrote the drivers
for this gateway for Microsoft NetBIOS, Banyan Vines IPC/SPC, and rewrote
approximately 60-70% of the driver for Novell IPX/SPX. Also wrote a
serial communications driver for the same terminal emulation framework.
. Also worked on other layers of the same terminal emulation framework
mentioned previously and fixed bugs as necessary. Was sent by the
customer to one of their customer's site to diagnose and repair a
previously existing bug.
Entek Corporation, Cincinnati, OH 1991-1994
Worked as a software engineer for this leading provider of vibration
analysis software products. Key accomplishments include:
. Worked on a team that designed and developed the first graphical version
of Entek's flagship vibration analysis software package for Windows 3.x.,
using Borland C++ and Gupta SQLBase. Designed and wrote classes for many
portions of the system using innovative techniques. Designed the logical
database layout for the new system. Designed and wrote utilities to
migrate data from the previous format to the new database, as well as a
utility to automatically adjust the database layout from version to
version of the software as necessary.
. Worked on and eventually became the development lead for a custom
client/server acoustical analysis product written for a fortune 50
company, designed and written to run on IBM OS/2 and using IBM DB2 for
data storage. The system utilized a driver architecture to enable
drivers to be written as needed to communicate with various types of real
time FFT and octave band waveform analysis instruments. The system was
designed to both acquire data and control the instruments
programmatically, store results in the database, and perform various
types of acoustical calculations on this data as needed. This was
written in C using Microsoft's compiler.
